“Jeff had acute appendicitis and fortunately the medical staff caught it very quickly,” Muschamp said in a statement. “His surgery went well and how long he is out will be determined by how his body responds, which could be two weeks.”

Florida begins fall practice Friday. The Gators open the season Aug. 31 at home against Toledo.

The 6-4, 236-pound junior starter led the Gators to an 11-2 record last season. He completed 63.7 percent of his passes for 1,646 yards, 12 touchdowns and five interceptions. He also ran for 408 yards and another four scores.

Jacoby Brissett transferred to N.C. State after last season, leaving the Gators a little thin at quarterback entering fall practice with Driskel sidelined.

Tyler Murphy was the team’s third quarterback last season, but didn’t take any snaps. That could leave redshirt freshman Skyler Mornhinweg and freshman Max Staver right into the mix. Sophomore Ryan McGriff could also see additional reps.
